4 Wetlands Transitional zones between land and water Many different species Swamps, marshes, bogs


6 Swamp

7 Marsh

8 Bog

9 Mangrove

10 Soil Often saturated long enough to become anaerobic (no oxygen) Wetland vegetation must be able to tolerate both flooding and the lack of oxygen in the soil.

11 Two Types of Wetlands Inland and coastal. Inland wetlands are freshwater ecosystems and include marshes, swamps, riverine wetlands, and bogs. Coastal wetlands may be either fresh or salt water and are affected by tides. Examples include tidal salt marshes, tidal freshwater marshes, and mangroves.

13 Observation vs Inference Observation is the process of gathering information using the five senses (sight, smell, etc.). Inference is the ability to use observations to make informed decisions. For example, a group of students working on the Wetlands... inquiry observe that the red-tailed hawk is larger than most birds, has a hooked beak, and sharp claws. They infer that the hawk is a carnivore based on these observations and consequently place the hawk at the top of several food chains they are brainstorming in their group.

14 Food Chains/webs A food chain shows the connections between individual organisms that depend on each other for energy. A food web shows all of the energy connections among living things within a community or ecosystem.
